No & Yes | As long as your Maintenance Agreement with Ivanti is valid they will support you, however if they determine that it is an OS issue they will ask you to Upgrade your OS.

If applicable – will the application support IE 11

Your version should work with IE 11, however if this is found to be the issue it will probably not be supported.

What is the versions roadmap

Well, you're at version 9.2.1.177 while the rest of the world is at 2018.1.0.261, and that would mean that you are currently around 30 builds behind everyone else. I believe that their goal is to release an Upgrade each quarter.

I would definitely re-instate your License Agreement if it is out of date, and then Upgrade to SQL Server 2016 & GoldMine 2018.1.0.261.
